USB device open failed.
Assume 8Mbit SPI Flash size.
Cannot start - Code 10 (Windows 8 or 10)
Are you using Windows 8 or 10? As mentioned in the listing and sound loader download page, some users have difficulties with certain Windows 8 and 10 machines (some work, some don't). Are you able to try using a different computer? If possible try using a Windows 7, Vista, XP machine as it should work perfectly fine on these.
If not due to an incompatibility issue as mentioned above, the only other cause is a faulty USB connection. Please make sure that the USB adapter or cable is securely plugged into both the PC and module. You can also try using another USB port on your PC. If you have another mini USB cable or adapter you can try to see if that fixes the problem. These units use standard mini USB cables/adapters which is common to many mobile devices such as MP3 players, digital cameras, photo frames, GPS systems, mobile phones, etc.
If you suspect the USB cable or adapter included with your order could be faulty, we can ship you another cable or adapter to try. Please let us know.
